Specification of Letters Patent.

Application filed January 7, 1911', Serial No. 601,451. Renewed October 5, 1917. Serial No. 194,988.

To all whom it may concern Be it'known that I, CHARLES GREnNoUeH MORTIMER, a citizen of the United States,

and a resident of East Orange, in the county of'Essex and State of New Jersey, have invented certain new and useful Improvements in Package-Sealing Devices, of which the following is a full, clear, and exact description, whereby any one skilled in the art may make and use the same.

The invention relates to devices or apparatus for supplying, in determinate lengths, strips in tape form, which may be employed for wrappingor binding or sealing packages; and relates particularly, to a machine which will accurately feed forward definite lengths of material, which lengths, may be varied at will during a single movement of the operating handle. As shown and described herein, the machine employs a strip of tape of indefinite length suitably supported and which is gummed upon one side. This strip during the operation of the machine is fed forward and moistened as to its gummed surface and cut off in predetermined lengthsby, a. continuous movement of the operating handle. S0 far as the apparatus shown is concerned, an ungummed strip of tape or paper may be employed by utilizing the reservoir or tank for the purpose of gumining the strip, in contra-dis tinction to using said tank with a simple liquid for moistening the gummed surface of a strip of tape.

The object of the present invention is to provide an apparatus which will feed the strip to a determined extent and'thereupon seversaid strip, so that strips of tape of determinate length, with an adhesive ."surface of proper consistency to be applied to a package or-othersurface, may be taken ofi from the' nachine.

A further object is to provide for a feed ing, cutting-ofiand moistening or adhesive application, during a single continuous movement of the. operating. handle.

A-further object is to provide means for delivering strips of various lengths, within reasonable latitudes, dependent upon the size of the machine and to maintain accuracyin the lengths of said strips. 1

A. still further object is to provide for the delivery of the strips of various lengths duly 'inoist'ened or. treated with adhesive, in

. In the accompanying drawings the numeral 1, denotes a base or support, at one end of which is a standard 2, having a supporting shaft 3,"upon which tension-plates 4, 5, are mounted upon opposite sides of a tape roll, 6, which may be of .any desired size and width and arranged to slip upon and be supported upon a shaft 3. The necessary tension upon the tape-roll 6, is ef-- arranged a casingit), which serves as an inclosure for the various working parts, as

iwellas 'a support therefor,

10- fected by screwing down the nut 7, against the extent of At either side of the casing, as herein shown, are extended casings 10, 11, which also serve to' inclose the working parts. The casing 10, is for convenience'provided on its outer face with a. dial 12 and on its peripheral surface with stop openings 13, which 'dial and stop openings, in conjunction' with an indicator-arm 14, having a pointer 15, and spring-pressed plug 16 serve, not only to indicate the length 0 tape which-will be fed from the machme, but actually determine, in conjunction with a pawl mechanism, hereinafter described, action of the feeding mechas ni'smL- Journaled in the' casings described, is a,

suitable main shaft 17, which is connected with an operatinghandle 18, and supports the indicator-arm 14, loosely mounted thereon as well as a pawl-carrier 19, fixed thereon.

I I A feeding ratchet 20, is secured, through a sleeve 21, to a gear 23, and these gears,

with their sleeve,.are loosely mounted upon the shaft 17, but move therewith, whenever the pawls borne upon the pawl-arm, 19, are

I 1 in engagement with the ratchet 20. 4

The gear 23, is in mesh with a pinion 24,

' connected with a feeding roll 25, upon a shaft 26, and said roll has I cooperating therewith, a presser-roll 27, suitably journaled, in the casing and gear-connected with the shaft 26, through gears 27, 28, so that the feeding roll'25, and presser-roll have a uniform movement. The .roll 27, is resiliently held against its 'cobperating feeding a cooperating blade 32, which, during the pause of the feeding action, is forced up-.

ward by a cam' 33, secured to the main shaft -17. The blade 32, is normally held in its normal position by a light spring 34, and as there is an abruptface 35, upon the 'cam 33,

I the spring 34, instantly returns the movable blade 32, to its normal position after" it has made a full cutting movement with reference to the stationary blade 30.

In advance of the cutting mechanism 7 there is arranged atank 36, havin suitably 7 roll 38, about which passes a band of resilient and absorbent material 39. The

"shaft 37, bearing the roll .38, is

journaled therein a shaft 37, whic bears a through a pinion 40, to the gear 23. here.- fore the feeding movement of the feeding rolls and the'forward feeding movement of the roll 38, are uniform. Overl yin the roll 38, and its tape 39, is, a presserrol 41, hav-' ing a series of disks 42, to' prevent adhesion. The pr'esser roll 41, is resiliently held eared against the upper surface of the tape by springs 43, arranged at each end of its axle.

The absorbent material 39, surrounding the roll is held in place by a weighted roll 43, which, of course, is located below the level of a liquid 44, or adhesive, as the case may be.

The moistening receptacle 36, is removable fromthe casing 9, upon removal of a slide-plate 45, which formsga closure for the front-side of the casing 9. It will be observed that the moistening device is a distinct unit, consisting of the casing 36, closed at the top by the roll 38, and its band of moisture or gum-conveyingmaterial so that there can be little or no'evaporation of the material contained in the receptacle, except such slight evaporation as may occur from the exposed surface of the band 36 where "it leads over the roll at the upper end of the casing.' The roll and its band, when in operation, are in constant movement and 7 therefore a full fresh supply, of moistening l1qu1d or adhesive,- is always submitted to one side of the tape, as itis-fed through the machine. v

At-the rear of the machine, as indicated in Fi s. 1 to 4 inclusive, there are a pair of rol s 46, 47, and a guide-plate 48. The. tape from the tape-roll is passed over the roll 46, about the roll 47 then across the guide- .plate- 48, to the feed-roll 25,.and presser-roll 27. It is then projected, past the cutting 01f device, between the moistening roller 38,

and its presser 42.

. The tape 49, being in coil form, naturally has a tendency to curl and .by passing it over the rolls-46, and about the roll 47, the

adhesive surface is broken, into minute particles, so that it will be delivered, in flat, un-

curled form, after it passes through the -mach1ne.

cated off the vertical center of the'roll 54.

To insure the flattened tape or paper strip being passed from the surface "of'the moistenlng roll 54, a bar 56, is pivoted in suitable P08111011 and has a series of blades 57,

which are formed to bear upon the cylinder of the roll 54', between sections of the fabric or moisture-conveying, material 58. These are so formed With regard to their advanced points 59, and their supporting shaft 56, in conjuction with the edge 60, of the tank that the strips of paper are led off withoutlia= bility of adhering to'the moistening material 58.- The barand its blades are illusneeaaw trated' in perspective in Fig. 9 and, of course, whether straightening rolls 50, to 53,- inclusive, are arranged directly upon the tank or in the position illustrated in 4, is quite immaterial. Merely for convenience they are shown in Fig. 10 in conjunction with the moistening tank.

The arml9, which is secured to the shaft 17, movedby the crank 18, bears a pawl mechanism'illustrated in detail in Figs. 6, 7 and 8. i This pawl mechanism has a clutchin and releasing action with reference to t e ratchet 20, which, as heretofore described, is connected through the sleeve 21, with the feedin gear 23, these various parts being loose y mounted upon the shaft 17. p

The pawl mechanism comprises a main pawl 61, pivoted as at 62, to the arm 19, and

provided with a cam-member 63, by which it may be moved and released from the ratchet 20, whenever it passes an adjustthrough the perforations. 13, and the casable trip 64:. This trip 64, as illustrated, consists of a member 65, projecting through a slotted opening 66, in the casing 10, and

may be clamped in anydesired position of adjustment along said slottedv opening by a nut 67. Its purpose and function is to raise the pawl 61," out of engagement with the ratchet 20, during the rotation of the operating handle and main shaft and thereupon stop the" feeding action; of the feed-rolls,

and appurtenant parts, with reference to y 'the tape or paper strip. A spring 68, normally tends to press the pawl 61, into engagement with its ratchet and in order to secure a definite and precise contact between the pawl 61, and its ratchet, the end of said pawl conforms to the ratchet teeth and has 'two pawl-points 69, 70, which. insure full engagement with one tooth of the ratchet, in

as much, as two ratchet teeth are actually engaged by the pawl-points 69, 70.

. Arranged upon the upper surface of thepawl 61, is a detent 71, which, when the cam member 63, is depressed by the plug 64,'is

engaged by a trigger or pawl 72. This pawl is pivoted to thearm 19, as at 73, 'and has an ofi-set pawl member 74, arranged inthe proper planeIto be engaged by-the spring plug 16, borne upon the arm 14:, and passing %bviously, the spring plug 16, may be ad- 'justed through any of the several openings 13, which correspond with the figures of. the dial 12, and theposition of this spring plug 16, determines. the point of .engagement, of the pawl 61, with its ratchet, for afeeding movement of the'tape.

The pawl 61, remains in contact with the ratchet 20, efi'ecting a feeding movement until the cam 63, is depressed by the plug 64. Thereupon the end of the trigger or pawl member 72, under the iuence of a spring 75, drops into the notch 71, and

holds the pawl 61, out of engagement with the ratchet 20, until the off-set awl member 74:, engages the plu 16. In ig. 6, the pawls are shown in a eeding positiomthe od-set pawl 74:, having been engaged by the plug 16, and depressed to release the feeding pawl 61. g

In Fig. 8 the pawl 61, is shown as released from the ratchet 20, by the contact of the cam 63, with the plug 64.

As soon as the parts are in the positionindicated in Fig. 8, the cutting off cam 33, is in position to move the blade 32, upward to cut ofi' thetape which hasbeen fed across the moistener and obviously, there is a dead ,feeding pawl 61. To revent possible retrograde movement of' t e shaft 17, a springpressed pawl 76, engages a fine toothed ratchet 7, the latter being secured to the shaft 17 These parts are best illustrated in Figs. 2 and '3.

From the above, it is apparent that a continuous movement of the operating handle 18', in one direction of rotation, effectsa feeding movement ofthe tape or paper strip to a redetermined degree, and instantly stops t e feed, giving a pause to the movementof the stripand thereupon severs the strip. There is a great advantage in such a mechanism, inasmuch as the parts ma be timed to a nicety in their operation an the strips may be accurately cut, at predetermined lengths, after they have been fed forward and moistened or gummed as to one side. The whole operation is accomplished during one cycle of mgvement of the operating mechanism in one direction and obviously, the operating shaft may be poweroperated or hand-operated to suit the exigencies of any; particularjcase. Furthermore, a greater latitude as to the length of strip fed may be secured in an apparatus of the character described, as a comparatively small angular movement of the shaft pause in the feeding action and movement may be utilized for the cutting ed operationand substantially the full movement of the shaft may be utilized for feeding. In the small machine herein shbwn, strips varying from %'to 13% inches maybe delivered and, of course, strips of any length between said figures may be served by adjusting the arm, 14., and its spring-pressed plug 16.

. The details of'the mechanism might be varied and arranged, in difierent mechanical forms, without departing from the spirit or intent of the invention, which .contem- .platesthe serving of strips with a surface made suitably adhesive, in predetermined lengths, by feeding the strip from a conto secure'by Letters Patent is:
